88彩票Product Introduction

　　Cross pan head with pad stainless steel screw refers to the use of 410 stainless iron (that is, an iron alloy containing a certain amount of chromium-nickel metal), and the head is a cross groove pan head with pad structure. Due to the high carbon content of this type of screw itself, oxidation will occur in the case of water, so the screw needs to be galvanized. That is to say, the zinc element is attached to the surface of the screw by cold plating or hot plating. Because the zinc element has strong oxidation resistance, it can play a better protective effect on the screw.
